Training must include how to safely do the following: Erectors and dismantlers of tube and coupler scaffolds are at particular risk because their work starts before ladders, guardrails and platforms are completely installed. One exception is when the scaffold platform is within 14 inches of the face of the work. Platforms may be coated periodically with wood preservatives, fire retardants, and slip-resistant finishes, provided they do not obscure the top or bottom wood surfaces. [29 CFR 1926.451(g)(2)], The employer must designate a competent person, who would be responsible for determining the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. Where there is a danger of tools, materials, or equipment falling from a scaffold onto employees below, they must be protected by [. Construction and loading must comply with engineered designs and manufacturers requirements. Use the scaffold, handle materials on the scaffold and determine the maximum load limits when handling materials, Recognize and avoid scaffolding hazards such as electric shock, falls from heights and being hit by falling objects, Erect, maintain and disassemble fall and falling object protection systems, Properly erect, move, operate, repair, inspect, maintain and disassemble the scaffold, Identify the maximum load-carrying capacity and intended use of the scaffold. If uplift could cause the components to separate, locking pins must be used and the components secured. 2. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. The number one scaffold hazard is worker falls. It is not all-inclusive and should be used as a starting point for the competent person to develop a checklist specific to the type of scaffold and jobsite conditions encountered. All diagonal . Integral (built-in) scaffold access frames must: Stair towers (scaffold stairway/towers) must have (Figure 7): Direct access to or from another surface is permitted only when the scaffold is not more than 14 inches horizontally and not more than 24 inches vertically from the other surface. [, In addition to meeting the requirements of, When vertical lifelines are used, they must be fastened to a fixed safe point of anchorage, independent of the scaffold, and be protected from sharp edges and abrasion. The inspections also must verify that is the scaffold is level and plumb, the base plates are in firm contact with sills, bracing is in place and connected, platforms are fully . The drawback to stairways, however, is the amount of space they are likely to take up in the overall structure. Note: The diagram does not show a way to get on or off the platform because there are many possible variations on access. Tip: Separation of frames can occur in high winds (uplift), or when workers climb endframes, overload the platform, or strike the scaffold with tools, materials, etc. [, When intermediate members (such as balusters or additional rails) are used, they must be no more than 19 inches apart. Materials being hoisted onto a scaffold must Connect the first cross- brace to the frame. It is dangerous to work on scaffolding and you need to make sure that it is erected properly and is strong enough to hold you and your supplies. Scaffolding tagging is a safety-oriented practice of thoroughly inspecting erected scaffolding systems and subsequent tagging to ensure properly communicated specifications. Requirements to prevent falls that apply only to these workers are addressed separately below. Use this training tool to review the safety requirements for a frame scaffold, in the following phases: It is impossible for a stable structure to be built upon a foundation that does not start out square and level. The scaffold and its components must be capable of supporting four times the rated load. The cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, level, and square. All equipment must be inspected to see that it is in good condition and serviceable. [. If using wooden planks, they must extend beyond the supporting This risk can be removed through proper clearance and maintenance. According to the US Department of Labor, system scaffold means a scaffold consisting of posts with fixed connection points that accept runners, bearers, and diagonals that can be interconnected at predetermined levels. Tube and coupler scaffolds over 125 feet in height must be designed by a registered professional engineer. Avoid propping the scaffolding frames up on the side of the bed. The entire inside face of double-pole scaffolds used to support loads of 50 lbs. The top edge height of toprails on supported scaffolds must be between 36 inches and 45 inches. The entire platform is attached to the fork. Plumb and level scaffold. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. 1. [, Each toprail or equivalent member of a guardrail system must be able to withstand a force of at least 200 pounds applied in any downward or horizontal direction, at any point along its top edge. 2. In general, a level is the easiest way to achieve the desired right angles. He fell, sustaining a concussion for which he was hospitalized. A scaffold must be erected "plumb, square, and level," because: If a scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift, potentially causing the overloading of one leg and the eventual collapse of the scaffold. Each section of the framework measured 6'5" high. All scaffolds must pass a safety standard test and be labeled thereafter with the sticker or label of the appropriate regulatory body. If solid sawn wood is used, it must be scaffold grade. [, Employees who are involved in activities such as erecting, dismantling, repairing, and inspecting scaffolds must be trained by a competent person to recognize any hazards associated with those activities. 6. We pride ourselves on exceeding our clients expectations in every interaction to make sure that our clients know how much we value and appreciate their business. Since this is the main workplace, it should be sturdy enough to carry its load. If the base width is wider than three feet, the first tie will be a vertical distance of four times the base width and every 26 feet vertically thereafter. Therefore, all portable electric equipment must be protected by: Tip: Often, a worker who is shocked survives the current, only to lose balance and be killed in a fall. Inadequacies in an affected employee's work indicate that the employee has not retained the necessary proficiency. Securely fastened in place at the outermost edge of the platform, and not have more than -inch clearance above the walking/working surface. Ties, guys, bracing and/or outriggers may be needed to assure a safe, stable scaffold assembly. The maximum intended load and the load-carrying capacity of the scaffold. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person. Specific requirements are described below. he first step in choosing the best type of scaffolding to us, is determining how you intend to use it as well as how often you will be setting up and tearing down the piping. They should be installed along all open sides and at both ends of platforms, except when used as a walkway, the platform is the main working area of the scaffold. [, Stair rails and handrails surfaced to prevent punctures or lacerations to employees, and to prevent snagging of clothing. They are erected in a manner that creates a usable ladder and provides good hand hold and foot space. Crossbracing is required on both front and back sides of each scaffold buck or frame. (Figure 4) [, Scaffolds shall be altered only under the supervision and direction of a competent person. Personal Fall Arrest System. Runners and bearers must be installed on edge. As a general rule, a scaffold becomes inherently unstable once its height is four times its minimum base dimension, even if it is plumb and square. Posts shall be erected plumb in all directions, with the first level of runners and bearers positioned as close to the base as feasible. Don't use bricks, blocks, barrels, or other unstable objects to level a scaffold. This training must be provided by a qualified person who understands the hazards associated with the type of scaffold being used and who knows the procedures to control or minimize those hazards. [, Scaffold platforms must be able to support their own weight, plus four times the maximum intended load. Ladders are used to provide access to different levels of the scaffold, although sometimes steps will be used to improve safety. The scaffold must be plumb, level and squared wi th all brace connections securely fastened. Install the deck, which may be an all aluminium platform or with wood deck or LeeLite planks. Wooden platforms (i.e. The ladder must extend 1 m (3 ft.) above the landing. The guardrail system shall be installed along all open sides and ends of the platform before being used as a work platform by employees. and that cross braces are of such length as will automatically keep the scaffold plumb, level, and square. Cross braces must keep the scaffold plumb, level, and square; All brace connections must be secured to prevent dislodging; Frames and panels must be joined together vertically by coupling or stacking pins or equivalent means; Frames and panels must be locked together to prevent uplift (separation of a This consists of scaffolding work connected with the operation/use of modular or prefabricated scaffolds; cantilevered material hoists with a max working load of 500kg, ropes and gin wheels, safety nets and static lines, as well as bracket scaffolds (tank and formwork) for licensing . All brace connections shall be made secure. When dismantling the scaffold, check to ensure that the scaffold has not been structurally altered in a way that would make it unsafe. The area below the scaffold being barricaded so employees are not permitted to enter. To check a scaffold for being plumb, use a level on two opposite uprights. If using wooden planks, they must extend beyond the supporting points By far, the most forgotten term of a door installation. General Guidelines. Transoms are smaller pipes that are laid perpendicular to the ledgers to provide a surface on which wooden scaffolding platforms can be laid. Most screw jacks will have a built-in stop so that the maximum height cannot be exceeded. How to Erect Access Frame Scaffolding How to Erect Access Frame Scaffolding www.worksafebc.com Select .
